Agreement When Words Come Between ("Interrupt") the Noun and the Verb

Interrupting Words

Interrupting words, such as "of" or "to," that come between the noun (when it is the subject of the verb) and the verb are not considered part of the noun (subject), so the verb does not have to agree with any of the words in the interruption.

For example:

The highest percentage of voters is (not "are") in favor of passing Proposition 94.

Either of the options is (not "are") consistent with the company's mission.
